Hey guys!

I've actually been registered here for a while but never posted much at all so lemme just say hi. After a buddy of mine bought the monoprice 9927 IEMS for me (still waiting for it) I decided to return to my audio hobby. I currently own the Koss Porta Pro and Sennheiser HD419. I've been thinking of getting the generic beats-looking pair and putting a proper pair of drivers/speakers in it (any difference between the 2?)
